Guys, if you saw a crying girl, what would go through your mind? Would you go up to her?

[In a World of my Own...?]

I was at school one day and I was so sad and everything was overwhelming me. I had my finals and A LOT stress at home, with my friends and guy problems (ergh), so anyway, I couldn't help it and I started crying. I didn't want anyone to see me, so I went off by myself and sat on a bench in our empty quad... or I thought I did. Some guy from my class saw me, and he was looking at me from across the quad. He would not stop staring at me. It just made me uncomfortable because he didn't come over or anything, he just kept staring at me. So later on, (about an hour later) when I had the class with him in it, he was looking at me a lot still all throughtout class! He seemed weird, like he was hesitant to say something to me, but it was awkward. By that time I'd stopped crying (obviously, lol) and I was trying to act better because I didn't want my friends to ask or be concerned or w/e. I was trying to just laugh and talk with my friends, which might have seemed odd to him I guess.. idk... So it just made me wonder. The way he was looking at me was so weird. I was wondering - if he was concerned - why didn't he just SAY something?

So guys, if you saw a girl crying on a bench by herself, would you come over? Just stare? What would you think?
